yes, they have chemical bonds therefore chemical change is used
Physical changes is change in property. Ex) change from solid to liquid....ice to water. Chemical change changes to different substances. Ex) rotting of fruit.
it is a chemical reaction because a new substance is formed when the wood rots
It is a physical change caused by chemicals. Chemical changes are phyiscal changes.
The coubustion of gasoline is an example of energy released by chemical changes
Physical and chemical changes are harmful to us.
Polymers are typically formed by condensation reactions, not hydrolysis. In a condensation reaction, monomers combine to form a polymer chain with the release of a small molecule like water. Hydrolysis, on the other hand, is the breakdown of polymers into monomers by the addition of water molecules.
A polymer is formed when monomers are joined together through chemical bonds. Polymeric macromolecules can have a wide range of functions and properties depending on the specific monomer units and how they are linked. Examples of polymers in nature include proteins, DNA, and carbohydrates.
Yes, if a substance changes its color and gives off a gas when heated, it is likely a compound undergoing a chemical reaction. The change in color and evolution of gas suggest that new substances are being formed through chemical bonds breaking and forming.
New molecules are formed.
All life be it animal or vegetable is formed of organic molecules. Humans can be thought of as 'electro-chemical polymers'.
A new substance is formed only after a chemical change.
Two examples of chemical changes are the rusting of iron and the combustion of gasoline. In chemical changes, new substances are formed due to the rearrangement of atoms.
Polymers are formed from monomers.
The type of chemical reaction that connects polymers together is dehydration synthesis.
When covalent bonds are formed between polymers, this is called cross-linking
This is for sure &*!@)!(@)!(@, this is because senior is too good for you.
Both chemical and physical changes involve a transformation of matter. In physical changes, the substance's chemical composition remains the same, while in chemical changes, new substances are formed as a result of a chemical reaction. Both types of changes involve the absorption or release of energy.
